PATHOGENESIS AND PROPER EVALUATION OF DILATED CARDIOMYOPATHY

Waleed Mohammed Omar Almahaili

This review highlights some essential concepts in the medical diagnosis of DCM patients, etiology and pathophysiology. The proper diagnosis is important in order to prevent consequences and for adequate treatment. We conducted electronic search for articles concerning dilated cardiomyopathy management, using major biomedical databases (CINAHL, EMBASE, MEDLINE) using comprehensive search strategies for all relevant articles published up to 2018. Dilated cardiomyopathy (DCM) is characterized by dilation and damaged contraction of one or both ventricles. Damaged patients have impaired systolic function and may or may not establish overt heart failure (HF). The here and now indications can include atrial and/or ventricular arrhythmias, and sudden death can happen at any kind of stage of the ailment. A diagnosis of dilated cardiomyopathy calls for proof of extension and damaged contraction of the left ventricle or both ventricles (eg, left ventricular ejection portion <40 percent or fractional shortening less than 25 percent).The disease is considered idiopathic if primary and secondary causes of heart disease (eg, myocarditis and coronary artery disease) are excluded by evaluation including history and physical examination, laboratory testing, coronary angiography (to exclude > 40 percent or fractional shortening less than 25 percent).
